Application tiled April 10, 1884. (X model.

To Z! whom, it may concern:

Be it known that 1, JAMES G. HALLAS, of \Vaterbury, in the county of New Haven. and State of Connecticut, have invented a new 1m 5 provement in Lamp-Burners, and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and

which said drawings constitute part of this specification, and represent, in

Figure 1, a side View of the burner, the parts in their normal or operative condition; Fig. 2, a sectional side view at right angles to the plane [5 of the wick-tube; Fig. 3, a vertical section througlil the base, cylinder, and wick-tube, the adjusting part of the burner removed; Fig. 4, a side view showing the chimney-rest in its raised position; Fig. 5, a horizontal section on line ;r 41-, looking down; Fig. 6, atop view of the base, cylinder, and wick-tube, the adjustable parts removed.

This invention relatesto an improvement in that class oflamp-burners in which the chimney-rest and cone are made movable vertically independent of the base and wick-tube, and whereby the wick may be trimmed or lighted without entirely removing the chimney-rest, cone, or chimney, the object of the invention being to make the construction such that the ehinmey-rest will be firmly held either in its up or down position 5 and in such construction, as more fully hereinafter described, and particularly recited in the claims, my invention consists.

A represents the base or burner constructed with the usual screw, a, to tit the lan1peollar. Central] y in this disk the wick-tube B is fixed. Around the wick-tube is afixed hollow eylin 4O der, D, extending from the extreme bottom of the base up to near the upper end of the wicktube, the upper end of the cylinder closed by a perforated top, E, which serves as apart of the air-distributer. The \viekndjuster F is also arranged in the usual manner transversely through the base. The top plate, I), of the base turns inward in a horizontal plane, but stops a little short of the cylinder 1), so as to leave a space between the cylinder D and the edge of the plate I), as seen in Fig. 6.

()n the cylinder D is a sleeve, G, arranged to slide freely up and down, and so as to pass down through the opening between the cylinder D and the edge of the top plate of the base, as seen in Fig. 2. From this sleeve two or more arms, H, extend outward and up ward, attached to and so as to support the chimney-rest I. The chimneyrest supports the dome-L in the usual manner, and at the bottom of the dome is the perforated air-distributer M, also of usualv construction, except that there is a central opening through it corresponding to the cylinder D, and so that when the chimney-rest is in its down position, as seen in Fig. 2, the upper end of the cylinder D closes the opening in the distributer M, the top E of the cylinder forming substantially a part of the air-distributer, but so that when the ehimney-restis raised, as seen in Fig. 4, then the distributer is taken away from the cylinder D, and a free space is left between the distributor or chinr ey-rest and the top of the wick-tube, so that the wick may be trimmed or lighted, and if lighted the central opening through the dis tributer permits the flame to pass up through 7 5 the distributer as the distributor is returned into the position seen in Fig. 2. It is necessary to hold the dome in its proper relation to the wick-tube in order that the slit in the dome may correspond to the tube. To this end a vertical slot, (7, is cut in opposite sides of the cylinder, and in a plane with the wick-tube, as seen in Fig. 5. Then through the sleeveG- and through the slots a pin, 0, is passed, made fast in the sleeve, but so as to slide up and down in the slots (1 as a guide to prevent rotation of the sleeve and the parts which it carries. As the sleeve descends below the wickadjuster, a notch, f, is out in opposite sides of the sleeve, so that the sleeve may pass to its extreme down position without interference with the wick-adj uster shaft. By opening into the base around the cylinder, to permit the sleeve G to extend down so near the bottom of the base, I am enabled to make a sleeve of suitable length without adding to the length of the burneras, for illustration, were the sleeve entirely above the base, then the height of the burner would be increased accordingly; or, it the sleeve were so short as to be adapted ney-rest and cone vertically adjustable with relation to the Wick-tube, nor do I claim, broadly, making it so adjustable on a cylinder around the wick-tube, the essential feature of my invention being the cutting away of that portion of the upper base-plate which adjusts the central tube, so that the outer or telescoping tube may pass down between the edge of said plate and the said inner tube, thereby making a shorter and more compact burner.

WVhat I do claim as my invention is- 1. The combination of the base, the wicktube fixed therein, the cylinder D, concentric with the base and surrounding the wick-tube, the top plate of the base constructed with a 20 recess between it and said cylinder, and the sleeve arranged upon the cylinder, so as to extend down upon the same through the space between it and the edge of the top plate of the base, and carrying the chimney-rest and cone, substantially as described.

2. The combination ofthe base,the wick-tube B, and cylinder D, both fixed to the base, the upper plate of the base extendinginward nearly to but so as to leave a space between it and the said cylinder, the sleeve G arranged on said cylinder, so as to pass down between it and the edge of the base, the cylinder being constructed with vertical slots 01, and the sleeve being provided with a. pin, 0, extending through said slots, the said sleeve carrying the chimney-rest and cone, substantially as described.
